What is the difference between displacement and deflection?
Displacement refers to the distance and direction of movement of a point or body from its original position, while deflection refers to the bending or deformation of a structure under a load or force. Displacement is an absolute measure, whereas deflection is relative to the original shape of the structure.
How you calculate deflection of a dial gauge of least count 01mm?
To calculate the deflection of a dial gauge with a least count of 0.01mm, you read the measurement indicated by the needle on the dial gauge after it has been set to the initial position. The deflection is the difference between the initial reading and the final reading on the dial gauge. Deflection = Final reading - Initial reading.
What is difference between null type and deflection type instruments?
Null type instruments require a null balance point to be achieved for accurate measurement, while deflection type instruments measure the quantity directly as a deflection on a scale. Null type instruments are more accurate but require more intricate adjustments, while deflection type instruments are simpler to use but may have lower accuracy.
What is the difference between deflection and idler pulley?
A deflection pulley is used to change the direction of a belt or chain, while an idler pulley is used to maintain tension in the belt or chain. In other words, deflection pulleys guide the belt around corners or obstacles, while idler pulleys help keep the belt taut and prevent slipping.
What Difference between null type and deflection type instrument?
Null type instruments require balancing the unknown quantity with a known quantity to obtain a measurement, while deflection type instruments measure the unknown quantity based on the amount of deflection of a pointer or needle. Null type instruments are more accurate but require more setup, while deflection type instruments are simpler to use but may have less precision.
